Facebook Experiments With Ads Targeting People’s Interests

The big promise of advertising on social networks has always been the ability to target members by their own self-proclaimed interests and demographics. Facebook, as expected, has quietly taken a step in that direction with its Facebook Flyers ads.The Flyers let you target by country, city, gender, age range, political views, relationship status, education level, workplace affiliation, or any keyword in a person’s stated interests. It’s that last option that could be really powerful. For instance, simply putting in different keywords into the Facebook Flyers ad-targeting page reveals that of the 19,951,900 Facebook members in the U.S., 101,000 are into rock climbing, 411,000 are into cooking, and 706,160 people are into traveling. Such targeting could theoretically allow advertisers to reach exactly the people they want, instead of the scatter-shot approach favored today. If you are a wedding planner in Salem, OR, for instance, there are 100 women on Facebook between 20 and 40 who live in Salem and are engaged. That’s pretty deep targeting. MySpace is also moving in this direction, allowing advertising by interest categories and sub-categories.
